Mirabilis longiflora

Interesting! Maybe I'll try that. Until now, I had considered M.
multiflora to be the hardiest, which indeed overwinters outside
unprotected for me (zone 7ish), though only from one of my two seed
sources - maybe there are individual differences?
I guess it's a little late now to try another longiflora and have it
established this year? I'll go and count my seeds ;-)

If the seed sowing goes well you may want to consider leaving a few outside. For at least the last five years mirabilis longiflora has overwintered on a sloped yet poorly draining(heavy loam) spot in the open garden. Winter lows here have been down to -10F, which appears to be too cold for the nearby Musa basjoo(which had been protected), yet I see Mirabilis sprouts up and growing.
